Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed February 26, 1908. Serial No. 417,946.

A further object of the invention is to so nlace the humidifier that both walls of the humidifier will be heated by being in close proximity to the radiating surface.

These 0 jects I attain as hereinafter set forth, refe ence being bad to the accompanying drawing, in which Figure is a side view, partly in section, illustrati my humidifier as applied to the center of radiator group; Fig. 2, is a plan view of F g. 1; Fig. 3, is a detached perspective view f ,the humidifier; Fig. 4., 1s a pers ective T of the cover; Fig. 5, is a sectional vi w illustrating a modification; Figs. 6 and 7,, are side views illustrating the bin midifier at one end of the roup of sections instead of in the center as i lustrated in Fig. 1; Figs. 8 and 9, are sectional views illustrating other modifications of my invention, and Fig. 10, is a side elevation of the structure shown in Fig. 5.

It will be. understood at the outset that my invention can be applied to any form of radiator made of sections and the design of the radiator may be varied, butwhere possible the design of the humidifier follows the design of the radiator so that when the parts are assembled the humidifier part resembles the radiator sections.

Referring in the first instance to Figs. 1 and 2, the radiator is made up of a series of sections A--A in the present instance coupled together at a-a forming a communication between the supply pipe 0 and the severalradiator sections. 0 is a valve for regulating the flow of steam or hot Water to the radiator, and a is a nipple or pipe coupling the two radiator sections together on each side of the humidifier-ii. This humidifier,

.in the present instance is made of cast iron and similar in shape to the radiator sections A and has a passage 2; in its lower end which extends from one side to the other of the humidifier, but does not communicate with the interior thereof; the nipple c'extends through this passage. At the n per end of the humidifier are passages b wlilch extend from one side to the other. These passages likewise' do not communicate with the interior. midifier section the same as in the radiator sections and are madeto receive the confining rods ee which fasten the sections together in the present instance, but other means of fastening may be resorted to withmy invention.

The arrangement of the through passages may vary according to design or type of radiator to which the humidifier is applied. In Fig. 8 I have shown a humidifier section B having a passage 1; at its lower end and a similar passage 6* at its upper end; this form is used especially in connection with hot water radiators.

In the present instance the humidifier section B has a removable cap D with a number of perforations d therein and this cap flanged at d; the flange extending within the radiator section B when the cap is in osition By this construction the cap can 0 removed and the humidifier can be filled with water or other liquid.

In the bottom of the humidifier section B is a drain opening 6 which can be provided with a suitable valve for drawing oil' the water when it is desired to empty the humidifier. The side walls of the humidifier are made preferably very thin and each .wa'll being in close proximity to a radiator section the vaporization of the water will be more rapid than where the humidifier is placed at the back of the radiator or on top of it as is the common practiceat the present time and a much larger area of thc'lmmidifier is subjected to heat. a

The humidifier section may he made as shown in Figs. 5 and 10, in which case the frame 1} is of cast metal and has inserted in it a'tank B made of sheet metal; the sides of the frame being open so that llm thin walls of the tank will he in close proximity to the i'adialor sections. Some types of radiators a re made entirely of sheet metal and in this event the humidifier soclion -would preferably be made of sheet metal, or a sheet metal humidifier may be used in connection with a cast metal radiator if found desirable.

In Fig. 7, l have shown the lllllllHllllll These passages are formed in the huout departing from the essential features of lilo llU

section B at one end of the radiator;'tllis sertion being similar to the section 15 illus trated in Fig. 1.

In Fig. (l. l hare shown a slight modification of the humidifier section; the section l" being secured to the radiator by rods 0 aml this set-lion B sto is short of the steam supply. hot water supp r or exhaust pipe.

in radiators in which a single pipe eommunicates with one end of the radiator, I may extend the humidifier section the full depth of the radiator section. as in Figs. 1 and 7, and attach it to the end of the radiator opposite, to the end of whieh the sup pl pipe is connected.

In Fig. 9, l have shown the humidifier section ll" with holes in the walls and the screw threaded nipple (1 passes through the holes and is adapted to threads in the radi ator sections A. gaskets being used bet ween the. Heetions to prerent leakage.

it will be seen from the above description that 1 can readily attach my improred hutnidifier to radiators already in position without. dismantling them. or I can place the humidifier in positional. any point in a group of radiator sections prior to their:

The

lions so that. the side walls of the humidifier will be heated to vaporize the water contained in the humidifier. and longitudinal rods tying the sections together, said rods passing through passages formed in the humidifier set-lion and securing said humidilier to the radiator sections.

l. The combination of a radiator made up of seetions connected together and to a suppl r pipe. a humidifier section adapted to contain lluid. said humidifier section having a through passage out of eonununieation with its interior. and a nipple extending entirely through the said passage and eoupled to a radiator section on eaeh side of the humidilier so that the circulation through the rad ie tor is not interl'ered with by the humidifier.

The combination of a radiator n'iade up ol' a eries of eonnected et-lions. a supply pipe attached to one end of the radiator. said radiator sections being spat-ed apart, a humidifier made to resem le a radiator section and hating a through passage extending from one side to the other. but not in communication with the interior 0] the humidifier. a nipple extending through the passage, and coupling the two radiator sections on each side of lhe humidifier. and a remorahle cap for the humidifier. said rap having perfora- 3 tiolt therein.

1. The combination of a radiator made up 2. The combination of a radiator made up of a series of vertically arranged sections.

with a vertically arranged humidifier section 3 'aped to resemble one of the radiator sections and assembled between two of the sec tions of the radiator, said humidifier section extending from one side of the radiator to the other.

3. The combination of a radiator made up of a series of sections, a humidifier made to resemble one ol' said sections and situated in close proximity to one of the radiator see i l l l i. The combination in a radiator made up of a series of sections coupled together, one section eommuniratiug with another, a lmmidifier shaped to conform to the general shape of one ol' the radiator sections and seured at the side to one of said sections so that the side of the humidifier will he in close contact with the side of the radiator section. a detachable. perforated cap for the said radiator section. said humidifier having an outlet at the base to draw ofi' the water.

T. The combination of a radiator with a humidifier shaped to resemble the shape of the radiator and attached thereto so that the side of the humidifier will be in close proximit) to the side of a radiator section, the humidifier being made in two parts, of which one eonsists of a frame open at. one side and the other part eonsists ot a tank mounted in the frame and haring its side exposed through the side opening thereof so that the water in the tank will be heated.

in testimony whereof. I hare signed my name to this specification in the presence of two subscribing witnesses.
